  • With histological changes, ontogeny and relative frequencies of bovine Sp-1/chromogranin(bCG)-, serotonin-, gastrin-, cholecystokinin-8(CCK-8)-, somatostatin-, S-100 protein-, polypeptide YY(PYY)- and glucagon-immunoreactive cells were investigated in the duodenum of the chicken embryos from 10 days of incubation to hatching. Histologically, pseudostraitified columnar epithelium were observed from 10 days of incubation to 14 days of incubation, thereafter these epithelium were differentiated to simple columnar epithelium. $Liberk{\ddot{u}}hn$ glands were observed from 18 days of incubation and goblet cells were detected from hatching. In the duodenum, bCG-immunoreactive cells were detected from 14 days of incubation and increased to 18 days of incubation, thereafter decreased with ages. Serotonin-immunorecative cells were detected from 14 days of incubation and increased with ages. Somatostatin-immunoreactive cells were detected from 14 days of incubation and CCK-immunoreactive cells were detected from 19 days of incubation. No gastrin-, S-100 protein-, PYY-, glucagon-immunoreactive cells were detected in this study.

  • Although importance of intrapancreatic neurons containing gastrin-releasing peptide (GRP) in control of exocrine secretion has been raised, the nature of GRP in the pancreas is unclear. Thus, the present study was undertaken to see distribution, content and molecular heterogeneity of immunoreactive GRP in the rat pancreas. Content of immunoreactive GRP in the rat pancreas was $2.99\;{\pm}\;0.66$ ng/g wet tissues determined by radioimmunoassay. Immunoreactive GRP was most abundantly expressed in the duodenal part among 3 parts of the pancreas; duodenal, body and splenic part. Vagotomy failed to change the content of immunoreactive GRP in the pancreas. Three distinct forms of immunoreactive GRP, very identical to GRP-27, bombesin-24 and neuromedin C, were observed in the rat pancreas by using reversed phase $C_{18}$ HPLC and Sephadex G-50 superfine column chromatography. Cell bodies of neurons containing immunoreactive GRP were scattered in pancreatic connective tissues and their nerve fibers innervated pancreatic acini and large ducts as determined by immunohistochemistry. The present results suggest that three distinct forms of GRP exist in intrapancreatic GRPergic neurons, which exert a stimulatory role in pancreatic exocrine secretion in rats.

  • Objectives: In Fujian Province, China, gastric cancer is one of the leading causes of mortality among all malignant tumors. Nanjing county and Minqing county are located in inland Fujian and have similar general demographics. However, the adjusted mortality rate of gastric cancer in Minqing was found to be much higher than that in Nanjing. We sought to explore factors associated with this increased risk of gastric cancer between the two counties. Methods: We recruited 231 and 224 residents from Nanjing and Minqing, respectively, and analyzed differences between their dietary habits, Helicobacter pylori infection rates, and concentrations of serum pepsinogen I, pepsinogen II, gastrin-17, and ratio of pepsinogen I:II. Results: Subjects in Minqing had more first-degree relatives who had been diagnosed with upper gastrointestinal tumor, more unhealthy dietary habits, a higher Helicobacter pylori positive rate, and greater proportion of abnormal serum gastrin-17 than those in Nanjing did. Conclusions: The factors that differed between these two counties might indicate that residents in Minqing have a higher risk for developing gastric cancer than those in Nanjing do.

  • 임신 7일부터 14일사이 paraquat(1,1'-dimethyl-4,4´-bipyridinium, 9m/Kg)를 모체에 경구투여하였을 때 태자와 출생후 흰쥐 위와 소장의 gastrin, somatostatin, gluca-gon, PP, CCK-8 및 serotonin면역반응세포 발생에 미치는 영향을 면역조직화학적으로 검색하였다. Paraquat 처리군의 면역반응세포는 대조군에 비해 늦은 시기의 태자부터 처음 관찰되며 출생전후 면역세포의 분포수도 차이를 보였다. 이로 보아 임신 중 모체를 통해 투여된 paraquat는 장내분비 세포의 분화를 지체시킬 뿐아니라 출생후 위장관의 성숙에도 영향을 줌을 알 수 있다.

  • The regional distribution and relative frequencies of endocrine cells were studied immunogistochemically (PAP methods) in the alimentary tract of the tree frog, Hyla areorea japonica, using specific antisera against serotonin, somatostatin, bovine Sp-1/chromogranin (BCG), cholecystokinin (CCK)-8, vasoactive intestinal polypeptide (VIP), gastrin, bombesin, secretin and pancreatic polypeptide (PP). Six kinds of endocrine cells were identified in this study, These immunoreactive cells were located in the gastric glands of stomach regions and in the basal portion of the epithelium of the intestinal tract or esophagus with variable frequencies. They were spherical or spindle-shaped. Serotonin-immunoreactive cells were observed in the whole alimentary tract including the esophagus. Somatostatin-immunoreactive cells were also detected throughout the alimentary tract except the rectum. CCK-8-immunoreactive cells were observed from the pylorus to ileum. Vip-immunoreactive cells were restricted to the rectum. Bombesin-immunoreactive cells were restricted to the fundic gastric regions and gastrin-immunoreactive cells were restricted to the pylorus. However, no BCG-, secretin and PP-immunoreactive cells were demonstrated in this study. In conclusion, the regional distribution and relative frequency of the endocrine cells in the alimentary tract of the tree frog were similar to other anuran species, but some differences which may be caused by feeding habits and species specification were also observed.

  • Objectives This study aimed to observe the effect of Hyangsayangwi-tang on the cisplatin-induced gastrointestinal dysfunctions in rats. Methods Four groups(each of 8 rats per group) were used in this study. Saline and distilled water treated control rats are Intact vehicle control group. Delayed gatrointestinal mortility was induced by intraperitoneal treatment of cisplatin 2mg/kg, once a week for 5 weeks(Cisplatin control group). Hyangsayangwi-tang aqueous extracts(HY) were orally administered in a volume of 5ml/kg, once a day for 14 days from 4th ciplatin treatmernt(HY group). Ondansetron 1mg/kg was subcutaneously treated, in a volume of 1ml/kg, as same as HY(ondansetron group). We measured the body weights, intestinal charcoal transit ratio, fecal parameters, fundus MDA, GSH contents and SOD, CAT activities, TPH and MAO activities, pyloric gastrin and serotonin contents with their immunoraective cells, colonic serotonin-immunoreactive cells, the histopathology of pylorus, fundus mucosa and colon. Results and Conclusions (1) The body weight gains, the small intestinal charcoal transfer rates, the fecal parameters(numbers, weights and water contents) were increased in HY, ondansetron group. (2) The inhibit of fundus antioxidant defense systems by cisplatin were decreased in HY, ondansetron group. (3) The pyloric TPH activities were increased and the pyloric MAO activities were decreased in HY group. (4) The pyloric gastric contents and the gastrin-immunoreactive cells were increased in HY group. And the pyloric serotonin contents and the pyloric and colonic serotonin-immunoreactive cells were decreased in HY group. (5) The pyloru atrophic changes and the gastric surface erosive damage regions by cisplatin were favorably inhibited by treatment of HY. HY, a representative Soeumin prescription improve GI dysfunctions and constipation retarded by cisplatin through modulations of GI enterochromaffin cells, serotonin and gastrin-producing cells and antioxidative systems. Especially HY showed the highest favorable effects more than those of ondansetron.

  • It is well known that both of acupuncture and moxibustion are effective for treatment of human disease. For years, they have been utilizing a electro-acupuncture (EA) and moxibustion in attempt to manage gastric symptom. However, the data of combined EA and moxibustion on clinical effectiveness is conflicting and the action of combineAd acupoints is not well known. BL21 and ST36 which belong to bladder Meridian and stomach meridian are acupuncture points frequently used for healing gastrointestinal disease in oriental medicine. The present study was conducted to see the effects produced by combined electro-acupuncture(EA) and moxibustion using BL21 and ST36 on serum gastrin level in rats. In experiment, male Spraque-Dawley rats(body wt 140-160g) were selected. EA (2 Hz, intensity ; 10 times muscle twitch threshold) was applied for 30 minutes to ST36 under halothane anesthesia. Moxibustion($1.6{\pm}0.3 mg$, 5 times of a day) was applied during 3 days to BL21 under halothane anesthesia. Synergy effects of combined EA and moxibustion might be in according to stimulated method and used acupoints. The change of serum gastrin levels produced by combined EA and moxibustion is shown after vagotomy. These data suggested that many factors, such as the selection of acupoints, the stimulated EA methods, are capable of affecting combined EA and moxibustion effects and those effects may be not related with nervous system.
